We develop one-dimensional model of an avalanche to examine the destruction of World Trade Center (WTC) 2 on September 11, 2001, after the building was hit by an airplane. Its main ingredient is the way the building opposes the progress of the avalanche, which is expressed in terms of a reaction force R at the location of the collapse front (a moving interface between the building and the avala...

nowadays, previously performance-oriented architecture of healthcare centers has been switched to creating a healing environment; and one of the most important pillars to create such an environment is omitting sound pollutions. today's hospital have chaotic situation regarding noise pollution not only in our country, but also in all over the world. the present study aims to provide a compl...

The Reliability/Availability/Serviceability (RAS) strategy for S/390T G5 and G6 is to continue the S/390 objective of providing Continuous Reliable Operation (CRO). The RAS strategy is constructed with a set of building blocks which work closely together: error prevention, error detection, error recovery, problem determination, service structure, change management, and RAS measurement and analy...

The physical states in a world-volume model of a non-critical 3-brane are systematically constructed using techniques of four-dimensional conformal field theories on R × S 3 developed recently. Invariant combinations of creation modes under a special conformal transformation provide building blocks of physical states. Any state can be created by acting with such building blocks on a conformally...

the main purpose of this study was to investigate the relationship between organizational culture and knowledge management in hamedan's jihad- agriculture applied-scientific higher education center (hjaas). denison's organizational culture model and the building blocks of knowledge management model were used for finding this relationship. a descriptive correlative methodology was used...

building contraventions have become one of the important dilemmas of many cities like tehran. the wide aftereffects of the contraventions and the large cost of removing their negative effects, make the reduction of the possibility of their occurrence essential. this paper tries to find the reasons and roots of building contraventions in order to prevent their occurrence through appropriate plan...

one  of  the  fundamental needs  for  the  human  is  to  have  a  workplace in  which  they  can  do  their  workappropriately. worldwide energy crisis necessitated the construction of official buildings with smaller space and less air ventilation. this led to the reduction in air conditioning, accumulation of the contaminants in indoor, increased exposure, health threat concerning the staff i...
